Biography
Born to the Slavs of Finland and the Velikiy Novgorod and Archangel regions of Russia, Mascazel became the chief of his father's tribe upon coming of age. By 410 AD he united the Slavic tribes and found a home in the warmer climates of Europe; however, he would have to take some territories to call his tribes' homelands.

Mascazel was accompanied by many family members, and swept southwards, besieging Colonia Dacia and Campus Iazyges, two colonies of the Eastern Roman Empire. His many attempts failed, costing him several soldiers and many of his family. After several major defeats, he attempted to flee from Roman general Posthumus Corialanus, but he was eventually cornered in eastern Germany and killed in battle.
